Social Distancing Scenarios

Scenarios evaluated

Here we evaluate the impact of 7 scenarios, each corresponding to a different contact rate. These scenarios can be understood in terms of:

• Effective \(R0\): The effective R0 this % decrease corresponds to
• % of original \(R0\): Percent of the original (pre-social-distancing) \(R0\) the effective \(R0\) this scenario represents
• % Increase from current: Percent increase from current (as of 2020-05-27) level of social distancing / contact rate

Scenario	Percent orig. R0	Percent increase from current R0	Effective R0
0	22.40%	0.00%	0.94
1	35.30%	57.60%	1.49
2	48.30%	115.60%	2.03
3	61.20%	173.20%	2.58
4	74.10%	230.80%	3.12
5	87.10%	288.80%	3.67
6	100.00%	346.40%	4.21
